观看免费视频 Nanotechnology being used in current products

I definitively believe that nanotechnology is around now, even in products that people use today. Again, it's one of these technologies that comes in in a rather invisible way. Clearly the key area where nanotechnology is needed, with respect to the industrial society we are in, is in making the silicon chips smaller and more performing. So the size of transistors today on these chips and certain aspects of a transistor, it's only a few nanometers that matter. You make a certain layer of oxide a bit too thin or a bit too thick by one or two nanometers and you're in trouble. So the ability to control dimensions in the microelectronics industry is really nanotechnology at the moment right now. In other fields, in biotech, in medicine, we're seeing the first signs of solutions that are based on nanoscale control, so that are really nanotechnology. But it's not a full-fledged technology yet.
